接好之後要安裝相關library，給編譯器來使用。
(之後會補下載連結)
裝好之後當然就是先開始寫程式啦~

// Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation
// is used in I2Cdev.h
#include "Wire.h"
// I2Cdev and MPU6050 must be installed as libraries, or else the .cpp/.h files
// for both classes must be in the include path of your project
#include "I2Cdev.h"
#include "MPU6050.h"
// class default I2C address is 0x68
// specific I2C addresses may be passed as a parameter here
// AD0 low = 0x68 (default for InvenSense evaluation board)
// AD0 high = 0x69
MPU6050 accelgyro;
int16_t ax, ay, az;
int16_t gx, gy, gz;
#define LED_PIN 13
bool blinkState = false;
void setup() {
// join I2C bus (I2Cdev library doesn't do this automatically)
Wire.begin();
// initialize serial communication
// (38400 chosen because it works as well at 8MHz as it does at 16MHz, but
// it's really up to you depending on your project)
Serial.begin(38400);
// initialize device
Serial.println("Initializing I2C devices...");
accelgyro.initialize();
// verify connection
Serial.println("Testing device connections...");
Serial.println(accelgyro.testConnection() ? "MPU6050 connection successful" : "MPU6050 connection failed");
// configure Arduino LED for
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// read raw accel/gyro measurements from device
accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);
// these methods (and a few others) are also available
//accelgyro.getAcceleration(&ax, &ay, &az);
//accelgyro.getRotation(&gx, &gy, &gz);
// display tab-separated accel/gyro x/y/z values
Serial.print("a/g:\t");
Serial.print(ax); Serial.print("\t");
Serial.print(ay); Serial.print("\t");
Serial.print(az); Serial.print("\t");
Serial.print(gx); Serial.print("\t");
Serial.print(gy); Serial.print("\t");
Serial.println(gz);
digitalWrite(LED_PIN,high);
}
以上是他給的範例，可以讀出RAWvalue，由於我們的功能是要偵測到動作就送出一個訊號
因此我們可以直接在loop函式內直接加上這樣功能的程式碼即可。
/
#include <EEPROM.h>
void loop()
{
int address = 5;
int value;
value = EEPROM.read(address);
if(ax<100)
{
EEPROM.write(address, 0);
}
if((ax>100)
{
EEPROM.write(address, 1);
}
if( value < 2 && value > 0)
{
digitalWrite(8,HIGH);
}
if( value < 1 && value > -1 )
{
digitalWrite(LED_PIN,LOW);
}
Serial.println(value);
}
如果直接用
if(gx <100)
{
delay(1000);
}
是可以讓他按一秒，但是delay函式會影響到全部的功能故要較少使用。
